arm and passes through the curved slot, cl, on As the vertical portion of the supporting arm is adjustable lengthwise, and the lateral part is likewise adjustable the fan-attachment may be suited to carriages of different styles and proportions. Such an arrangement as here described will be found very useful and effective in protecting children from the heat, and also from being annoyed by insects.

The horizontal part, D of the fan-arm has a bracket, 3, provided with a suitable clamp, 25, for holding the stick, u, of a parasol, so that the parasol, H, will be above and the revoluble fan, F, below the said supporting part, D

Having thus described my invention what I claim as new and desire to secure by Letters- Patent is:-

1. In a wheeled vehicle, the combination of a supporting arm pivoted on an axle of the vehicle concentric with a wheel on said axle, and extending vertically alongside the body of the vehicle to the top thereof where it has a lateral extension projecting over the said body; a vertical shaft in a bearing on said lateral extension and carrying horizontal fan blades at the lower end and a pulley at the upper end; suitable pulleys at the angle of the supporting arm; a driving pulley fast with the vehicle-wheel and concentric therewith; and a belt connecting said driving pulley and the fan-shaft pulley and passing over the pulleys at the angle of the supporting arm.

2. In a wheeled vehicle, the combination 0 a bearing-block fastened on an axle of the vehicle and having a radial slot entering one side to receive the said axle, and a circular head concentric with the axis of the axle; a supporting arm having an arc-shaped crotch engaging said circular head and adjustably fastened thereto; a rotary fan carried by said supporting arm; a driving pulley mounted to rotate with a wheel of the vehicle which is concentric with the circular head of the bearing-block; and a belt connecting said pulley with the rotary fan.

In testimony whereof I affix my signature in the presence of two witnesses.

MERRILL H. TRIPPE.
